Hello sir, which will be a better option between NITIE Mumbai and IIM Indore …there are many controversies about Indore that batch size being huge it's difficult to get placed there?

It is subjective and it completely depends on your goals and your preferences, and how much the IIM tag matters to you. If you are really keen and want to have a career in operations and especially supply chain management then you can/should go for NITIE. 

For all other streams go for IIM-I without any second thought. The placement is good there even with the big batch size and all, and why consider yourself at the bottom of the batch before even entering the institution? Even if you are able to keep yourself in the top 50 percent you will get a good and lucrative job and package. 

Below is a table comparing the two on the basis of fees, and packages;

And the Average Package of the top 50% of the batch INR 34.04 LPA (NITIE)
